A National Strategy for Adaptation to Climate Change was prepared in Finland in 2005. To implement the Adaptation Strategy, an Action Plan has been prepared in the Ministry of the Environment in cooperation with the Ministry of Agriculture and Forestry. The concrete measures of the Action Plan related to biodiversity, land use and construction, environmental protection and the use and management of water resources should be implemented by the environmental administration. The most essential impacts of climate change requiring adaptation measures in the environmental administration include the increase in the occurrence and intensification of extreme weather events such as floods, storms and heavy rainfall, and changes in the quantity and seasonal variation of water resources and in biodiversity.
